Illustration of Ames Test protocol (created in BioRender). The Ames test is a widely used assay for evaluating the mutagenicity of a chemical substance. It uses several strains of auxotrophic Salmonella typhimurium, known to carry a mutation that prevents histidine biosynthesis, an essential amino ac...
Ames test investigates the potential of the test compound to result in a back mutation that causes the gene to regain its function and grow in a histidine-free medium. Cyprotex offers the Ames test as an early stage assessment of genotoxicity using a min

We describe here a mini version of the regulatory Ames test protocol that allows a significant reduction of the quantity of test substance needed (300 mg) but remains applicable to all Salmonella strains used in the regulatory protocol. In a preliminary study, 10 in-house chemical compounds have...
These protocol differences make data analysis difficult and by that compromise the results. Therefore, given the importance of evaluating medicinal plants for mutagenic potential, it is necessary for the tests to be carried out according to the recommended guidelines. Our data also generated a ...

concentrations around the dose contributing to the initial questioned response, altered metabolic activation conditions (if S9 was used), or modification of the test protocol, e.g., preincubation or vapor phase exposure instead of plate test, or a different solvent (if solubility may be in ...
The purity and molecular confirmation of each dye were determined, and the microplate agar protocol (MPA) was used. Dyes were tested at the limit of solubility in single and concentration‐response experiments using seven strains without and with metabolic activation except for anthraquinone dyes ...
